We've found some very freaky deals to Frankfurt on US Airways, the kind you definitely do bring home to mamma. Like the London deals we mentioned earlier, these are mostly useful for extended trips of 3 to 4 weeks starting mid-to-late July. Terms and availability vary by city, but they will no doubt go quickly (we're talking hours, here, not days) so better get 'em fast or mamma might get mad!
